is that LED you describe the one labeled cr-10 on the secondary board?  it stays off ----
meanwhile , ive turned the unit on a few times over the last few days and it stays unresponsive with over 30 of the LED's on in kind of a random pattern.
what would you suggest ?
--ive fixed a few things on my polaris before and replaced the membrane switch panels---   the thing sounds damn awesome--- and i have a number of other synths--- this has such a wonderful tone. 


(also-- for your information  i had this polaris on  a two tiered rack with a DSI polyevolver which was  connected to a slaved polyevolver rack----all on one power strip------ now the Polyevolvers  are acting weird with the sounds being corrupted  in the memory of one or both units--- they were identically programmed  before the gig. Now they sound different with the same  patch names/numbers  on the screen.    Im trying to contact DSI about this problem ...........   i wonder if some thing happened with the power that night at the club--  i now have 2 messed up synths).
